The logical point of departure in thinking about non-violence,
is its opposite, that which it denied: violence. I'm reminded
first of all, of the violence of the Olympians, specifically,
Zeus, as chronicled in Aeschylus drama Prometheus Bound, where
the Titan is chained "forever" to a crag for having given fire
to mankind, and rails against the injustice of the gods. As I
wrote recently, I consider the sacrifice of Isaac on Mount Moriah
a turning point in Hebrew theology inasmuch as it transformed
the god prepared to do violence against his own people into the
invisible god with the unspeakable name whose violence initially
at least is limited to the Egyptians. Consistent non-violence
appears only in Isaiah, where the Messenger of God is described:

7 He was oppressed, and he was afflicted, yet he opened not his mouth:
he is brought as a lamb to the slaughter, and as a sheep before her
shearers is dumb, so he openeth not his mouth.

8 He was taken from prison and from judgment: and who shall declare
his generation? for he was cut off out of the land of the living:
for the transgression of my people was he stricken.

9 And he made his grave with the wicked, and with the rich in his death;
because he had done no violence, neither was any deceit in his mouth.

10 Yet it pleased the LORD to bruise him; he hath put him to grief:
when thou shalt make his soul an offering for sin, he shall see his seed,
he shall prolong his days, and the pleasure of the LORD shall prosper
in his hand.

11 He shall see of the travail of his soul, and shall be satisfied:
by his knowledge shall my righteous servant justify many;
for he shall bear their iniquities.

In other words: All's well than ends well, applies also to the non-violent.
